PRODUCTION OF KRAFT ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To gain a method for producing a kraft adhesive tape excellent in curability of a releasing layer, enabling a pressure sensitive adhesive layer to be formed immediately after the formation of the releasing layer and excellent in a releasing performance. SOLUTION: This method for producing a kraft adhesive tape comprises forming a releasing layer made of a silicone mainly comprising a branched organopolysiloxane having alkenyl groups combined with silicon atoms located at the ends of the organopolysiloxane which is expressed by the formula, wherein R1s are each a monovalent substituent selected from the group consisting of H, a 1-4C lower alkyl group and phenyl group; R2 is a 2-10C alkenyl group; (a1)+(a2)+(a3) is 30-1000; and (b) is an integer of 1-5 and being crosslinked with an organohydrogenpolysiloxane on one side of kraft paper, and then forming an adhesive layer made of a rubber-based pressure sensitive adhesive on the other side of the kraft paper.
